Trying not to sound like an arrogant prick, but lets face it: Average is actually pretty dumb. Average suggests majority, and as we all know, the majority is usually wrong/under-educated/ignorant. The average person is unable to think for themselves, beyond believing that they actually do think for themselves.
Now, I am not saying that I am, like, the smartest person ever, but I do have the intelligence to make my own decisions, while also being able to alter my own opinions when I receive insight from another person.
Because I care more about the the thinking process then I do about being right (logic over pride) most of the time, I would consider myself to be pretty far above average.
of course, we also have to consider the difference between wisdom and Knowledge. Are both needed to be, truly, intelligent? Or neither?
